This sriracha spread is a three-ingredient condiment — mayonnaise, sriracha, and mustard — that takes five minutes to mix and keeps in the fridge for the whole cookout. It punches noticeably harder than plain mayo and works on beef, chicken, or veggie burgers without overpowering everything else on the bun. Make a big batch before guests arrive and you’re done.
Why this recipe works
The real trick here is the mustard. It does two things: adds a mild tang that keeps the spread from tasting like straight spicy mayo, and emulsifies slightly so the mixture holds together instead of weeping sriracha onto the bun. Because you’re working with mayonnaise as the base — which is already an emulsion — the whole thing stays stable at room temperature for the length of a normal cookout without breaking or separating. That stability is exactly why this scales so well: mix a cup or two at once, park it in a bowl with a spoon, and it stays ready without any attention from you.
Ingredient notes
- Sriracha: Standard Huy Fong works. If you’re using a different brand, taste before adding — heat levels vary more than you’d expect between sriracha-style sauces.
- Mustard: Yellow mustard gives a milder, slightly sweeter result. Dijon is sharper and a little more complex. Either works; just pick one and stick with it when scaling up so the flavor stays consistent.
- Truffle salt: Listed as optional and it genuinely is. Skip it if you don’t already have it — regular kosher salt does the job, and buying truffle salt just for a pinch in a condiment isn’t worth it.
- Mayonnaise: Full-fat mayo holds the texture better than light versions, which can turn slightly watery when mixed with acidic ingredients like sriracha.
What can go wrong
- Spread tastes flat even after adding more sriracha: You probably need salt, not more heat. A pinch of salt sharpens all the other flavors and is usually the missing piece.
- Spread is too thin and slides off the burger: This happens with light or store-brand mayo that has a higher water content. Switch to full-fat mayo, or stir in an extra teaspoon and let it sit for a few minutes — it firms back up.
- Heat level is inconsistent across a big batch: Sriracha settles in the bottle, so the first squeeze can be thinner than the last. Shake the bottle before measuring, especially when you’re doubling or tripling the recipe.
- Spread tastes harsh right after mixing: Give it five minutes. The sriracha and mustard mellow slightly once they’ve had a moment to blend into the mayo, so don’t keep adjusting immediately after mixing or you’ll overshoot.
- Spread picks up fridge odors overnight: Store it in a sealed container, not plastic wrap over a bowl. An airtight jar keeps the flavor clean for days.
Storage and reheating
Store the spread in an airtight container in the refrigerator for up to five days. Because it’s mayo-based, don’t leave it sitting out for more than two hours — that’s the standard safe window for mayo-based condiments at room temperature, and it applies whether you’re at a cookout or just leaving it on the counter. This spread does not freeze well; mayo breaks when frozen and thawed, leaving a greasy, separated mess. Make only what you’ll use within the week. No reheating needed — it’s a cold condiment.

Your questions, answered
Can I make this spread the night before a cookout?
Yes, and it actually tastes better after a few hours in the fridge. The flavors blend more fully overnight, so making it the night before is a smart move when you’re prepping for a crowd.
How do I scale this up for a large group without it getting too spicy or too mild?
Mix a single batch first, taste it, then multiply your adjusted ratios — not the original ones. Sriracha heat can compound unexpectedly when you scale up, so locking in your preferred ratio on a small batch before multiplying saves you from a too-hot or too-bland big bowl.
What’s the best way to serve this at a cookout so it doesn’t get warm and runny?
Put the spread in a small bowl nested inside a larger bowl filled with ice. It stays cool and thick for the duration of most cookouts without you having to shuttle it back to the fridge every thirty minutes.
Can I use this spread on chicken burgers, not just beef?
Absolutely — it works well on chicken burgers, especially crispy fried ones where the heat and tang cut through the richness of the breading. Just make sure your chicken patty is cooked to an internal temperature of 165°F (74°C) before adding any condiments and serving.
Is there a dairy-free or egg-free swap for the mayo?
Vegan mayo works as a straight one-for-one swap and holds the texture well. Brands made with aquafaba or pea protein tend to be the most stable and won’t thin out the spread.
